A total of twenty Candidate Plus Trees of Grewia tiliifolia have been selected from the predominant growing areas of Southern India viz., Karnataka, Kerala, Telangana and Tamil Nadu by comparison check tree method. The trees were selected based on comparative superiority of selected trees for growth attributes viz., height, girth at breast height (GBH), and crown width. Keywords: Candidate Plus tree, Grewia, Southern India, CPTs, Comparison check tree method INTRODUCTION area in the world, India supports more than 15 Indian forests have undergone a tremendous per cent of the world’s population. The mean change in the past few decades and are annual increment (MAI) of Indian Forest is presently under a great threat. The excessive meager of 0.5 - 0.7 m3 ha-1 compared to the use of forests resources leading to forest global average of 2.1 m3 ha-1 (Srivastava, degradation, which may become irreversible if 2005).
